Hundred Regiments Offensive

The Hundred Regiments Offensive was a major offensive carried out by the communist divisions of the National Revolutionary Army against the Imperial Japanese Army in northern China from 20 August to 5 December 1940. The Communist Party of China decided to prove that it was contributing to the Second Sino-Japanese War by assisting a Kuomintang offensive against the Japanese forces in the north, facing the North China Area Army. Zhu De led 20 regiments on the offensive against the Japanese, while 80 more regiments would surprise him by joining him without being ordered to do so. The Chinese blew up bridges and tunnels and ripped up track, damaging the Japanese war effort, rendering the Jingxing coal mine inoperable for six months. The offensive was the greatest communist Chinese victory of the war.
